JOSEPH O. VAIL, OF MAPLES MILL, ASSIGNOR TO HIMSELF, AND THOMAS M. MERCER, OF LEiVISTOi/VN, ILLINOIS.-

COVER FOR MILK-CANS.

SPECIFICATION forming part of Letters Patent No. 407,975, dated July 30, 1889.

Application filed January 22, 1889- Serial No. 297,134. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH O. VAIL, of Maples Mill, in the county of Fulton and State of Illinois, have invented anew and Improved Cover for Milk-bans, of which the following is a full, clear, and exact description.

My invention relates to covers for milkcontaining vessels, the object of the invention being to provide for the ventilation of such vessels, but at the same time to prevent the entrance thereto of dust, insects, &c.

To the end named the invention consists, essentially, of a cover made up of an upper plate and an under apertured plate separated from the upper plate by spacing-strips, provision being made for the ventilation of the space between the two plates, all as will be hereinafter more fully described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of my improved milk-can cover. Fig. 2 is a view of the under side thereof. Fig. 3 is a cross-sectional view on line x of Fig. 2. Fig. 4 is a perspective view of a modified form of cover, the cover being inverted and parts being broken away; and Fig. 5 is a perspective view of the cover shown in Fig. 4, representing the same as it appears when arranged in connection with the milk-crock.

In the drawings, 10 represents an upper plate, and 1 1 'a centrally-apertured lower plate. In the construction shown in Figs. 1, 2, and 3 the plates 10 and 11 are separated by spacingstrips 12, which are held to place by nails, screws, or other fastening devieessuch as those shown at a-thus leaving open spaces 1) upon opposing sides of the cover. Then this construction is employed, I protect the aperture 0 of the plate 11 by wire-gauze 13. This form of cover, when placed upon amilkcontaining vessel, will permit the escape of all noxious gases, and at the same time prevent the entrance of insects or dust, the gases finding their way outward through the aperture 0 and the side openings 1), as will be readily understood.

Instead of leaving the openings 1), I might construct mycover with a continuous spacing-strip, this construction being shown in Figs. 4 and 5, wherein 14 1% are spacing-strips arranged between the plates 10 and 11. In this construction the space between the two plates 10 and 11 is ventilated by means of apertures 15, formed in the plate 11, said apertures being located, by preference, near the corners of the plate. In this-case the-wirenetting 13 may be dispensed with.

By means of such a cover as the one above described I provide for the thorough ventilation of the milk, and I also provide for the stowage of one vessel above the other,whereby great economy of space is secured.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a milk-can cover, the combination, with an upper solid plate, of a lower apertured plate and spacing-strips arranged between the plates, substantially as described.

2. In a milk-can cover, the combination, with the upper plate, of a lower apertured plate and spacing-strips arranged between the plates at opposite sides thereof, the space between the plates being open upon the other sides, substantially as described.

3. In a milk-can cover, the combination, with an upperplate, of a lower plate formed with a central aperture 0, spacing-strips 12, arranged between the plates and upon opposite sides thereof, the other sides of the structure being open, and wire-netting secured to the lower plate to cover the aperture 0, substantially as described.
